CAR-AXLE BOX.

SPEClIFICATION forming part of Letters Patent No. 315,278, dated April 7, 1885.

Appncanon sied auguran, 1884. (N model.) l A l provement in Car-Axle Boxes, of which the following is a full, clear, and exact description, reference being had to the accompanying dra'wf ings, forming part of this specification.

The improvement relates toa device to prevent the pilfering of the brasses,which is done by jacking up the truck and then pulling ont the loose brass.

Figure 1 is a longitudinal vertical section at 11, Fig. 2. Fig. 2 is an end view with the cover of the axle-box elevated. Fig. 3 is a horizontal section at 3 3, Fig. 2. Figs. tand 5 are perspective views of the two tumblers enlarged. Figs. 6, 7, 8, and 9 areV enlarged detail sections, showing different positions of the tumblers and the lock-pin.

A is the axle, B the bearing-brass, and C the dustshield. No novelty is claimed for these, nor for the cap or cover D,which closes the aperture through which the lubricating material is introduced. This aperture is also used for the removal of worn brasses and the introduction of new ones. When the brasses are to be changed, the truck is jacked up at that part so as to' lift the axle-box (or greasebox) E, (relatively to the axle,) and thus loosen the brass B, which may be then drawn out. Many brasses are stolen in this way after night, l and to prevent this I extend a lock-pin, F, across the axle-box before the end of the brass, so that the brass cannot be taken out while the pin is in this position.

To enable the removal of the brass B, the pin is drawn endwise into the position shown in dotted lines in Fig. 3. To allow this, however, the pin and both the tumblers G and H must be placed in a certain position,which can only be done after night by the use of alight. The tumblers are rings, like a thick washer, which turn freely on the pin, and through which the pin may be freely slipped when they are allin the proper position therefor. At other times a tooth, f, on the side of the pin comes in contact with the tumblers.

f is a cross-pin at the point of the lock-pin, which prevents its withdrawal from the axleof indentations, y, at one side around its Acentral bore. The tooth fv may` enter either of f,

these recesses, and in this case the tumbler and the pin turn'together, and the pin ,cannot be i box. One of the tumblers, G, has a number.

retracted to allow the removal ofthe brass. p

Both tumblers have anotch, g',throug`h"which the tooth can pass. There is also a notch, e,

at one side of the pin-hole'in the axle-box, so

that when the pin is turned with its tooth f in line with the notch e, and the two tumblers are turned so that their notches g are in the A same line, the pin can be drawn out sufficiently to allow the removal ofthe brass. The tumblers are in a recess, e'. Theinner wallof this has a small recess, e2, in which thetooth f rests when the pin is in its inner position, and thus the pin is restrained from turning. Thetooth is held in the recess by the tumbler G, except when either of the recesses g or notch g are made to coincide with the recess e, when the p tooth can be drawn from the recess e into the y recess or notch g or g', as the case may be.

The recess e2 is shown in line with the notch e;

but this is not necessary, as it may be located in any other position atthe side of the pinhole. rlhe tumblers have upontheir periphery a mark or marks. 71 to indicate to any person, by the .use of a light, if after night. when they are in position to allow the withdrawal of the pin, and the head of the pin may also have a mark or marks,h.,for the same purpose. These peripheral marks may be made all around the tumblers and pin-head F', and distinguished by Agures, letters, or other marks,

as found in permutation-locks, and for a simi-` lar purpose. The head F of the pin extends over and hides the notch e when the pin is in its inner position, and when in this position the point of the pin enters a recess in the opposite side of the grease-box E. and 3.) When the pinis in this position, the tooth f is in the recess e?.

As long as the tumbler G remains" in the po` sition shown in Fig. 6 the tooth cannot be re moved from the recess c2,- but if Vthis tumbler is turned into the position shown'in Fig. 7 i that is, if one of the recesses g is brought` in line with the tooth-the pin F may be drawn yout a short distance and the tooth drawn into (See Figs. 2

(See Figs. 6 and 8.)

ICO

the recess g. The pin cannot now be drawn out any farther, although it can be turned around. On the other hand, if the two tumblers are set in the position shown in Figs. 8 and 9, the tooth f can be drawn from the recess e'l through the notches g ofthe tumblers and e ofthe grease-boX, and the pin drawn out into the position shown in dotted lines in Fig. 3, and in full lines in Fig. 9, allowing the removal of the brass B. It will thus be seen that after night a light will be needed n the removal of the pin, and thus any attempt to steal the brasses will be detected by a watchman.

l. A movable pin or bar in front of the bearing-brass of a car-axle boX, for thepurpose set forth.

2. A movable pin or bar in front of the bearing-brass of a car-axle box working endwise of the pin in the wall of the grease-box and having a tooth thereon, and one ormoretumbl'ers upon the pin, substantially as and for the purpose set forth.

3. A movable pin or bar in front of the bearing-brass of a car-aXle box working endwise of 2 5 the pin in the wall of the grease-box and having a tooth thereon, and a tumbler turning on the pin and having recess orrecesses to receive the tooth of the pin, and a notch allowing the tooth to be drawn through the tumbler, substantially as set forth.

4. The combination, in a car-axle box, of a movable pin or bar in front of the bearingbrass working endwise iu the wall ofthe greasebox and having a tooth on the side, two or more tumblers loose upon the pin, having each a notch, allowing the passage of the tooth, the wall of the grease-box through which the pin works having a notch at one side of the pinsocket, allowing the passage of the pin-tooth when the pin is in a certain position.
